Exhibit 99.1

DuPont Delivers Record First Quarter Earnings of $1.61 Ex-items

Innovation and Productivity Drive Strong Performance

·                  First quarter 2012 earnings, before significant items, were $1.61 per share versus $1.52 per share in 2011.  Reported earnings per share were $1.57 versus $1.52 in 2011.

·                  Sales of $11.2 billion were up 12 percent versus the prior year.  This reflects 8 percent higher local prices, 1 percent currency headwind, 2 percent lower volume and 7 percent net benefit from portfolio changes. Sales in developing markets grew 15 percent.

·                  Segment pre-tax operating income, excluding significant items, increased $252 million, or 12 percent versus the prior year, principally due to Agriculture, Performance Chemicals and the benefit of prior-year acquisitions in Nutrition & Health and Industrial Biosciences.

·                  Agriculture delivered 16 percent higher sales and an 18 percent increase in pre-tax operating income, excluding significant items, versus last year’s first quarter. This reflects strong global business performance and an early start to the North American and European selling seasons.

·                  The company’s productivity initiatives continued on track with improvements of approximately $100 million each for fixed costs and working capital.

·                  DuPont reaffirmed its full-year earnings outlook range of $4.20 to $4.40 per share, which represents 7 to 12 percent growth versus 2011, excluding significant items.

“DuPont’s market-driven science and commitment to innovation and productivity are winning in key markets, despite economic headwinds early in the first quarter,” said DuPont Chair and CEO Ellen Kullman.  “Around the world, we are bringing our science closer to local markets by collaborating with customers and partners in our new DuPont Innovation Centers.  We are prioritizing our R&D portfolio to deliver food, energy and protection solutions for the world’s growing population.”

Global Consolidated Sales and Net Income

First quarter 2012 consolidated net sales of $11.2 billion were 12 percent higher than the prior year, including 7 percent attributable to portfolio changes.  Local prices were 8 percent higher with increases in all regions.  The 2 percent decline in total company volume principally reflects strong Agriculture segment volume gains in all regions offset by lower volume for most segments in Asia.  The table below shows regional sales and variances versus the first quarter 2011.

* Europe, Middle East & Africa

First quarter 2012 net income attributable to DuPont was $1,488 million versus $1,431 million in the first quarter 2011. Excluding significant items, net income attributable to DuPont was $1,520 million versus $1,431 million in the prior year.  The improvement principally reflects earnings growth in Agriculture and Performance Chemicals and income from a prior-year acquisition.  Higher selling prices more than offset increased spending for sales, marketing and research and development, and higher costs for raw materials, energy and freight.

The following is a summary of business results for each of the company’s reportable segments, comparing first quarter 2012 with first quarter 2011, for sales and PTOI, excluding significant items.  References to selling price are on a U.S. dollar basis, including the impact of currency.

Agriculture - Sales of $4.1 billion were up $576 million, or 16 percent, with 8 percent price and 8 percent volume gains.  Seed sales growth reflects strong global performance with robust North American corn sales, a strong, early start to the European season and commercial success in Brazil’s Safrinha season.  Crop Protection product sales growth was underpinned by particular strength in insect control product volumes and price gains across the portfolio.  PTOI of $1.3 billion improved 18 percent on higher volume and price, offset in part by input cost increases and unfavorable currency impact.

Electronics & Communications - Sales of $677 million were down 17 percent on 18 percent lower volume.  Sales reflect continued soft demand in photovoltaics, partially offset by increased demand for smart phones and tablets.  PTOI of $33 million declined from lower volume and plant utilization.

Industrial Biosciences - Sales of $288 million and PTOI of $41 million reflect the acquisition of Danisco’s enzyme business.  PTOI includes $5 million of amortization expense associated with the fair value step-up of acquired intangible assets.

Nutrition & Health - Sales of $808 million and PTOI of $83 million reflect the acquisition of Danisco’s specialty food ingredients business.  PTOI includes $21 million of amortization expense associated with the fair value step-up of acquired intangible assets.

Performance Chemicals - Sales of $1.9 billion were up 6 percent, with 16 percent higher selling prices and 10 percent lower volume. Higher selling prices more than offset higher raw material costs.  Lower volume reflects continued softness in titanium dioxide, particularly in Asia Pacific.  Global demand for titanium dioxide increased sequentially.  PTOI of $512 million increased $118 million on higher selling prices.

Performance Coatings - Sales of $1.1 billion were up 6 percent on higher selling prices.  Higher selling prices across all regions and market segments offset higher raw material costs.  Continued strong demand in OEM motor vehicle and industrial coatings, particularly in the North American heavy duty truck market, was offset by softening in refinish primarily in southern Europe.  PTOI of $87 million increased on higher selling prices, mix enrichment and continued productivity actions.

Performance Materials - Sales of $1.6 billion were down 6 percent, with 10 percent lower volume and a 2 percent reduction from a portfolio change partially offset by 6 percent higher selling prices.  Demand improved in the automotive market, particularly in North America, but was more than offset by continued softness in industrial and electronics markets.  Higher selling prices offset higher raw material costs.  PTOI of $240 million decreased due to lower volume.

Safety & Protection - Sales of $941 million were down 2 percent, with 5 percent lower volume, partially offset by 3 percent higher selling prices.  Volume was lower on continued softness in industrial markets.  Higher selling prices reflect value-based pricing.  PTOI of $100 million decreased on lower volume and higher spending for growth initiatives.

Exchange Gains/(Losses)

The company routinely uses forward exchange contracts to offset its net exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of its operations. The objective of this program is to maintain an approximately balanced position in foreign currencies in order to minimize, on an after-tax basis, the effects of exchange rate changes. The net pre-tax exchange gains and losses are recorded in Other income, net and the related tax impact is recorded in Provision for (benefit from) income taxes on the Consolidated Income Statements.

As shown above, the “Total Exchange Gain (Loss)” is the sum of the “Subsidiary/Affiliate Monetary Position Gain (Loss)” and the “Hedging Program Gain (Loss).”

Reconciliation of Base Income Tax Rate to Effective Income Tax Rate

Base income tax rate is defined as the effective income tax rate less the effect of exchange gains/losses, as defined above, and significant items.
